With no one out and a runner on first base, a bunt is being used for the purpose of moving the runner over to second base. This is considered a sacrifice bunt because the intent is to surrender the out at first to put the runner in scoring position. A coach should be looking for this type of strategy in a tight ball game usually later in the game. And with no one out there is much higher chance of this happening because it is so much easier for an opposing coach to sacrifice an out if they have two more to “play with”. If the coach on defense suspects a bunt then it is wise to move the first and third basemen in on the grass. If the bunt is executed properly then the only play for the defense to make is going to be at first base. However, if the ball is bunted too hard then it is possible for a play to me made that would cut down the lead runner. A very poorly bunted ball fielded by the pitcher could actually be turned into a double play. Another scenario could also see the bunt attempt popped up. If a fielder catchers the pop up in the air then they should look to double off the runner on first. It is likely that the runner knows of the bunt and could be running hard to make sure they advance. If the runner is focusing too much on getting to second base then this could leave them vulnerable to be doubled off after a bunt is popped up and caught in the air. A sacrifice bunt will be less likely with one out and a lot less likely with two outs.
